Should I See a Doctor???

So... I'm about a full month late for my last period, meaning it's almost time for my next period. I've had few pregnancy symptoms, like having to pee every 20-30 mins, being super hungry, two cravings (watermelon and Reese's), getting tired around 7pm, light cramping with no bleeding, back pain today, and nausea yesterday and today without getting sick. My stomach is also really hard around the bottom of my belly. I've taken three at-home tests and all have said negative, though I've read stories from other females that they were 4+ months before their at-home tests resulted in a positive test. My debate is whether to wait a couple weeks to see if I get my next period, or to go ahead and see a doctor (considering my pregnancy would be high-risk)???
